To all whom it may concern Be it known that I, RALPH H. Maca citizen ofthe United States, residing at Centralia, in the county of-Lewis andState of Washington, have invented new and useful Improvements inGasolene- Vaporizers, of which the following is a v specification.

- The invention has for its primary object to produce a saving in theliquid fuel utilized in'the operation of internal combustion engines andat the same time increase the 4 power and efficiency of'the engine.

The invention provides a device to be introduced in the'passage betweenthe carbu: reter and cylinder of an internal combustion engineforsupplying air to the gaseous mixture and insuring a thoroughcommingling of suchair with the mixture, whereby any particles of thefuel contained in such mixture will be vaporized with the result that ahomogeneous mixture is supplied to the engine with the result that amore per- 4 feet combustion is assured.

The invention consists of a chamber conprovided with a plurality of airinlets, gaseous mixture to take a tortuous path as well as to insure athorough agitation of the gaseous mixture which is free from any freeparticles of fuel and when ignited pro-- duces gases which give off aminimum amount of, carbon to deposit upon the cylinder and adjunctiveparts.

The invention further provides a mixing chamber containing hollowbaflles in which the incoming air is received, said baflies having aplurality of minute openings for the discharge of the air in a manner toinsure its blending with the gaseous mixture to increase its combustiblequality with the .result that the power of the engine is materiallyincreased and thereby enabling the fuel consumption to beproportionately reduced for the amount of developed power.

The invention consists of the novel features, details ofconstruction andcombination of parts, which hereinafter will be more particularly setforth, illustrated and claimed.

such bafiies. causing the Patented Feb. 16, 1915.

Qorresponding and like parts are referred to m the followingdescription, and lIldlcated in all the views of the drawing, by the samereference characters.

The numeral 1 designates a chamber which may be of any construction orsize, the same being located in the passage by means of which thegaseous mixture is supplied to the engine. This chamber as shown isadapted to be coupled to the 'carbureter 2 and the manifold 3. For thispurpose the chamber is provided at opposite ends with flanges'which areapertured to receive the bolts or fastenings by'means of which-thechamber is secured to the respective parts. The flanged ends of thechamber are formed with openings, the one for the inlet and the otherfor the outlet of the gaseous mixture. One side of the-chamber is openand is adapted to be closed by means of a plate 4 which may be securedto the chamber in any manner when placed in position. Inner projections5 are located upon opposite sides of the chamber near the open end andare adapted to engage and limit the inward movement of a plate 6 towhich the several baflles are attached. An air space 7 is formed betweenthe plates 4 and 6. The plate 4 is formed upon its inner side withprojections 8 which engage the plate 6 and hold it in proper position. Aplate 9 is located at the opposite side of the chamber 1 and has theseveral baflies attached thereto. The plate 9 is of a length to pass bythe inner projections 6 therebv admitting of the baiiies and theirsupporting plates 6 and 9 being removed from the chamber 1 or' placed inposition therein. The baffles are provided in two sets as indicated at10 and 11. The baffles 10 consist of single plates which are corrugated,and arranged in spaced parallel relation and at an angle to straightlines connecting the inlet and outlet openings of the chamber 1. Thebaffies 11 are hollow and are arranged in parallel and spaced relationand at an angle the reverse of the bafllles 10. The faces of the baflies1 1 are corrugated or fluted. A plurality of minute openings 12 areformed in the edges of the hollow baffles 11, and-constitute outlets forthe air which is to be mixed with gaseous mixture passing through thedevice.- Openings 13 are formed in the plate 6 in position to registerwith the spaces inclosed by the several hollow baflles 11 and suchopenings 13 estabdriver so as to be operated to unseat the lishcommunication between the air space 7 and the spaces of the baffies 11.

The air to be mixed with the gaseous mixture is admitted into thechamber 1 in regulated quantity which is at all times under control ofthe driver. For this purpose a. suitable valve mechanism is provided andattached to the chamber 1 and as shown such valve mechanism comprises acasing 14 which is proyided in one side with a tapered opening 15'whichconstitutes the air inlet. l'he casing 14 is carried by the plate 4 andis in communication with the air space 7 by means of an opening 16. Avalve seat 17 is formed at the inner end of the opening 16 and a lugvalve 18 is adapted to close thereon and cover the inlet openings 15 andthe opening 16. An expansible spring 19 arranged Within the casing 14normally holds the valve 18 seated. A connection 20 extends from thevalve 18 to a control lever, not shown, 'Within convenient reach of thevalve 18 more orless toregulate the air to be supplied to the gaseousmixture for tempering and gasifying the same.

With reference to the valve casing 14 the opening 15 is the inlet andthe opening 16 the outlet. By having the opening 15 of tapering form theamount of air admitted may be regulated to-the best possible advantage.Movement of the valve 18 uncovers or covers both 'the air inlet andoutlet as will be readily understood. When the valve 18 is closed thegaseous mixture passes direct to the engine without having anyadditional air added thereto, but the bafiles act in a measure asheaters to break up any particles of fuel that may not vaporize. When itis required to add air to the gaseous mixture the valve 18 is moved touncover the openings 16 and 15 and the air passing through such openingsinto the space enters the hollow bafiies 11 and escapes therefrom inminute jets through the openings 12 and mingles with the gaseousmixture,such air and mixture being caused to combine and blend by the action ofthe baffles in causing the air and mixture to take a tortuous path, theblending being further facilitated by the ribs or projections formed bycorrugating the baffles'. Should it be required at any timeto gainaccess to the interior of the chamber 1 the baflies and their supportingplates 6 and.9 may be withdrawn throwing the open side ofthe chamberclosed by means of the plate 4.

From the foregoing description, taken in prislng a chamber having anconnection with the accompanying drawing, the advantages of.theconstruction and. of the method of'operati'on will be readilyapparent to those skilled in the art to which the invention appertains,and while I have described the principle of operation of the invention,together with the devices which I now consider 'to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative and that such changes-may, be made when desiredas are within the scope of theinvention as claimed. v 1

Having thusdescribed; the invention, what is claimed as new is 1. Adevice to be located in the fuel-passage by means of which gaseousmixturejis" supplied to an internal combustion engine,

the same consisting of .a chamber; hollow j baiiles arranged within thechamber and provided with minute outlets and means for supplying air inregulated quantity to the spaces of such hollow baflles.

2. A device to be'located in the fuel passage by means of which gaseousmixture is supplied to an internal combustion engine,

formed With minute outlets and means for supplying air in regulated airspace of thechamber. v I

4. A device of the character specified comair space at one side,.twosets of corrugated 'baflies arranged within the chamber, the baliies ofone set being oppositely inclined to the baflies of the quantity to theother set andone set of bafiies being hollow and in communication 'withthe air, space of the chamberand formed-with a plurality of outlets andmeans for supplying air in regu- Lated quantity tothe air space-ofthe'cham- In testimony whereof I afiix my signature in presence oftwowitnesses. p RALPH H. MACDONALD.
